Now, we have two S4 objects and we can use them in our code as necessary. For example, we can change the phone number.

# Check if it is really an S4 object: isS4(my_cust_bank) ## [1] TRUE # Change the phone number and check: my_cust_bank@phone = 987654321 # change the phone number print(my_cust_bank@phone) # check if it changed ## [1] 987654321
